SPECIFICATION forming part of Letters Patent No. 297,408, dated April 22, 1884:.

Application filed January 15, 1884.

To all whom, t 117,0;7/ concern:

Be it known that I, ORANGE JULL, of the town of Orangeville, in the county ofDufferin, in the Province of Ontario, Canada, miller, have invented a certain new and useful Snow- Plow; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of the invention is to devise a 1o snowplow capable of removing the snow with great rapidity and throwing it some distance from the track of the plow; and it consists in the peculiar construction, combination, and arrangement of parts, as hereinafter more particularly described andclaimed.

Figure l is a perspective view of my snowplow. Fig. 2 is a sectional side elevation of the same. Fig. 3 is a perspective detail of the cntting`blade. Fig. 4 is a perspective view In the drawings'like letters of reference indicate corresponding` parts in each figure.

A is a cylindrical case having an opening, a, made in its circumference, which opening is preferably provided with a hood, b, shaped so as to direct anything forced from the cylindrical case by centrifugal force away from the track of the plow. This case should be in diameter a little less than the width of the 3o cutting it is desired to make.

c are side anges flaring from the cylindrical case. These flaring ilanges may extend entirely around the case A; but it is not necessary that they should, although for deep 3 5 snow it may begpreferable to have them so eX- tended. -f

d is a bottom flange curved from the side flanges inwardly to a point at or near the edge of the parallel side of the cylindrical case.

B are a series of cutting-blades shaped substantially like the blades of a screw-propeller, and designed to fit into and inclose the open end oft-he cylindrical case A. Vhile I think it will bepreferable to form the cutting-blades in the manner shown, I am of the opinion that a single blade caused to revolvev at a very high speed might answer in a measure, if not quite as well as the four blades shown, the object of the bladev or blades be- 5o ing to slice the snow from the bank being op- (No model.)

erated upon, and to cause the snow thus sliced olf to fall behind theblade, where it comes in contact with the fan-blade O, which is revolving in the opposite direction to that in which` the cuttingblade B is moving. In the drawings I have shown my fan composed of four fan-blades; but it will of course be understood that this number may be increased or decreased, as in the case of the cutting-blades.

Vhen the snow is thrown upon the revolving 6o blades G by the actionpof the blades B', the f1 centrifugal force produced by the ,revolving ofthe blades O will cause the snow acted upon by them to ily through the opening a, and as the said opening a is protected by the hood 65.

b the snow thrown through the opening is directed aivay from the track made bythe I i plow. As it is important that the blades B and C should revolve on the same center, I

attach the blade or blades O to the hollow 7o shaft D, which is carried 'in suitable bearings, and has xed to it the beveled pinion E.

E `is a shaft j ournaled within the`hollow shaft D, and having fixed on its front end the blade or blades B. t 7 5 I-I is a beveled pinion keyed or otherwise fastened to the shaft F, and arranged to mesh with the spurwheel G, which meshes with the pinion E, as indicated. Consequently the revolving of the wheel G causes the shaft D, with 8o its connections, to revolve in one direction, while the shaft F, with its connections, revolves in the opposite direction. This form of driving the blades B and O will, I think, be found the simplest and most effective plan for operating this portion of my invention..-`

I may mention here that I propose Vdriving the shaft of the spur-wheel G by an independl ent steanrengine; but of course I do not conne myself to any particular inotor, nor is 9o there anything special in the arrangement of mechanism by which motion is communicated from the driving-motor to the parts described as embodying my invention.

It will be noticed, as I have before stated, that the bottom flange, (l, is curved from side f flanges inwardly to a point near the parallel sides of the case A, or, as might be more properly stated, near the revolving blades B. This curved form ofilange is designed so that. Ioo

no great weight of snow can accumulate in front of the cutting-blade B, while at the same time the flange d strengthens the side flanges, c, and also acts as a sort of shovel to raise the snow to a point near the cutting-blades B.

Vhile my snow-plow is specially designed for use on railroads, it of course might be used for removing drifts on a highway; and I may also say that the mechanism arranged as I have described would make a very effective excavator for the removal of loose earth. I therefore do not confine myself to the cmploynient of my plow strictly to the removal of snow from a railroad-track.

Before pointing out specifically the points I desire to claim as myinvention, I may niention that the main plane of the cutting-blades B lies at about right angles to the plane of the fan-blades C, and that when a series of cutting-blades B are used they are located so as to revolve in front of and inclosing the open front of the cylindrical case A, in which construction I think it important to have a hole or opening, e, made in thebaek of the cylindrieal case, as shown.

I am aware of Iatent No. 87,989, and make no claim to the construction shown therein.

XVhat I claim as my invention isl. In an improved snow-plow in which a cutting-blade is caused to revolve in front of and in the opposite direction to a revolving fan-blade, a hollow shaft arranged to support and revolve with the fan-blade, in combination with a shaft journaled within the hollow shaft and arranged to propel the cuttingblade, each of said shafts being provided with a pinion meshing with the gear-wheel G, substantiall y as and for the purpose specified.

2. rIlhe fan-blades G, fixed to and propelled by the hollow shaft D, and the cutting-blades B, fixed to and propelled by the shaft F, which is journaled within the shaft D, in co1nbination with a cylindrical case, A, having an opening, a, in its circumference, and flaring side flanges, c, with a bottom flange, d, curved from the side flanges, c, inwardly to a point near the revolving blades B, substantially as and for the purpose speci-fied.

3. A series of fan-blades revolving within an open-front cylindrical case having an opcning, a, in its circumference, and an opening, c, in its back, and a hood, b, over said opening a, in combination with a revolving disk formed by a series of cutting-blades, B, and located at the open front of the cylindrical case, substantially -as and for the purpose specified.
